\brief 1) replay(optional Coordination, optional CompositeSubscription)
|
||||
Turn a cold observable hot, send all earlier emitted values to any new subscriber, and allow connections to the source to be independent of subscriptions.
|
||||
|
||||
2) replay(Count, optional Coordination, optional CompositeSubscription)
|
||||
Turn a cold observable hot, send at most count of earlier emitted values to any new subscriber, and allow connections to the source to be independent of subscriptions.
|
||||
|
||||
3) replay(Duration, optional Coordination, optional CompositeSubscription)
|
||||
Turn a cold observable hot, send values emitted within a specified time window to any new subscriber, and allow connections to the source to be independent of subscriptions.
|
||||
|
||||
4) replay(Count, Duration, optional Coordination, optional CompositeSubscription)
|
||||
Turn a cold observable hot, send at most count of values emitted within a specified time window to any new subscriber, and allow connections to the source to be independent of subscriptions.
|
||||
|
||||
\tparam Duration the type of the time interval (optional).
|
||||
\tparam Count the type of the maximum number of the most recent items sent to new observers (optional).
|
||||
\tparam Coordination the type of the scheduler (optional).
|
||||
|
||||
\param count the maximum number of the most recent items sent to new observers (optional).
|
||||
\param d the duration of the window in which the replayed items must be emitted
|
||||
\param cn a scheduler all values are queued and delivered on (optional).
|
||||
\param cs the subscription to control lifetime (optional).
|
||||
|
||||
\return rxcpp::connectable_observable that shares a single subscription to the underlying observable that will replay all of its items and notifications to any future observer.
